I have recently obtained a Sterling Cook Stove in operable condition. Style Number 66STN. 43" wide, 28" deep, 34 1/2 high at cook top, 52 1/2 high at back plate. No cracks or chips in the porcelain, operates by natural gas and kerosene, has hot water heater on left side of stove. I have found little or no information on the web. Would you please provide history or information for this stove and an approximate value.
